Polycrystalline CoO-Bo Hybrid as Proficient Electrocatalyst for Addressing Kinetically Sluggish Anodic Reaction in Water Splitting.

Herein, we demonstrated that a polycrystalline cobalt oxide/borate (CoO-Bo) hybrid catalyst prepared by coprecipitation followed a simple annealing process with a viable boron source of less hazardous ammonium borate, an efficient electrocatalyst for the oxygen evolution reaction (OER). The borate species in the crystalline cobalt oxide lattice provides a tunable polycrystalline morphology with a defect-rich lattice and numerous grain boundaries in the CoO-Bo hybrid electrocatalyst, which significantly boosts the OER activity compared to the crystalline counterparts of CoO and precious IrO in a harsh alkaline electrolyte (1 M KOH). The borate modulated CoO-Bo achieves a 10 mA/cm geometrical current density for the OER with a very low overpotential (η) of 271 mV and small Tafel slope of 34 mV dec, in an inert glassy carbon (GC) support, while only requiring η of 267 and 32 mV dec in a 3D nickel foam (NF) support at the same current density.

Expert Panel Consensus Recommendations for Allergic Rhinitis in Patients with Asthma in India.

Allergic rhinitis and asthma are commonly coexisting conditions, significantly impacting patient health and quality of life. Despite their interrelation, diagnosing allergic rhinitis in patients with asthma remains challenging, leading to underdiagnosis and suboptimal management. The expert consensus engaged a modified Delphi method involving 29 experts including pulmonologists, ear, nose, and throat surgeons, and allergologists.

General Dentist's Knowledge and Attitude Towards Non-Surgical Endodontic Retreatment in Tunisia: A Cross-Sectional Study.

Introduction: Root canal retreatment is carried out in cases where previous endodontic therapies failed and involves the removal of root canal filling materials, followed by cleaning, shaping, and obturating of the canals.

Aims: : The objective of this study was to collect information regarding attitudes, methods, and materials employed during the non-surgical endodontic retreatment (NSER) by general dentists working in Sousse Governorate, Tunisia.

Materials And Methods: A descriptive cross-sectional survey was conducted among 147 general dentists working in the Sousse Governorate, Tunisia, from May to November 2021.

Polycyclic Aromatic Hydrocarbons (PAHs) in aquatic ecosystem exposed to the 2020 Baghjan oil spill in upper Assam, India: Short-term toxicity and ecological risk assessment.

This study focuses on the short-term contamination and associated risks arising from the release of Polycyclic Aromatic Hydrocarbons (PAHs) due to the 2020 Baghjan oil blowout in upper Assam, India. Shortly after the Baghjan oil blowout, samples were collected from water, sediment, and fish species and examined for PAHs contents. The results of the analysis revealed ΣPAHs concentrations ranged between 0.
